Summary:                    exten = 2813,n, Queue(test,c,,,,,,inqueue)  craches
when went into invalid extension
Description: 
With empty [default] context and no context set for queue test, I had this
in context [local_phones]:

exten = 2813,1, Answer
exten = 2813,n, Queue(test,c,,,,,,inqueue)
exten = 2813,n, Hangup

exten = 2813,n(inqueue), NoOp(Call taken by ${MEMBERINTERFACE})
exten = 2813,n, Return

Yes, that's a misinterpretation of the gosub-statement, I have realised.
When a call came into 2813, and answered by a queuemember, asterisk shuts
down silently:

    -- Executing [2813 at local_phones:1] Answer("SIP/3004-082b9b10", "") in
new stack
    -- Executing [2813 at local_phones:2] Queue("SIP/3004-082b9b10",
"test,c,,,,,,inqueue") in new stack
    -- Started music on hold, class 'default', on SIP/3004-082b9b10
    -- SIP/3010-082bf340 is ringing
c042*CLI> 
Disconnected from Asterisk server
Executing last minute cleanups
Asterisk ending (0).


The first time it happened, I also got:
[2008-09-24 09:41:20] WARNING[23423] pbx.c: Channel 'SIP/3003-b816e6d0'
sent into invalid extension 's' in context 'default', but no invalid
handler

When investigating issue http://bugs.digium.com/view.php?id=13548, I found that
gosub
handling in app_queue was just completely wrong, mostly
because the channel operations being performed were being
done on the incorrect channel.

With this set of changes, a gosub will correctly run on
the answering queue member's channel. There are still crash
issues which occur if there are dialplan syntax errors, so
I cannot yet close the referenced issue.
